Controlled Burn Scheduled at Sweetwater Wetlands: Taming Mosquitoes and Invasive Species

Tucson Water and the Tucson Fire Department are set to commence their annual controlled burn at the wetlands on the Northwest Side starting Tuesday. This initiative aims to mitigate mosquito populations and manage invasive vegetation while also serving as a training exercise for wildland firefighters.

The area, located near Interstate 10 and West Prince Road, will be closed to the public beginning at 8 a.m. on Tuesday and will remain inaccessible until Friday, October 4.

Officials have warned that residents in the vicinity may notice smoke, light ash, and the distinct smell of burning vegetation. Those sensitive to smoke are encouraged to take precautions or avoid the area altogether.

This annual project has been a collaborative effort since 1999, with the low-intensity fire contributing to Tucson Water’s Mosquito Abatement Program. By eliminating dead vegetation, the burn disrupts habitats that support mosquito larvae, thereby enhancing the effectiveness of larvicides.

In addition to addressing mosquito control, the burn helps manage invasive plant species and provides essential training opportunities for local wildland firefighters.

The second phase of this year’s burning is scheduled for November 13, ensuring that any habitat regeneration for native species occurs before the winter migratory bird season.

Each burn is designed to last only one day, although residual smoke and odors may linger for one to two days following the event. The operation is contingent on favorable weather conditions; however, should the weather forecast change, the initial burn could be rescheduled for October 3, with the second phase postponed to November 19.
